This is for a Blade MSR / MCX2.

The 9116 shaft is 4mm.

Looks a little expensive and heavy?

I have a feeling the std V912 swash will do the trick (has bushing) or another alternative is the ZR Z101 top with 9116 bottom. I had to file off the small retaining lip on the 9116 bottom then use CA to fix. Received my turnigy servo's today, now just waiting on the V912 PCB and I can test the new ZR Z101 head.

You were right on

[QUOTE=Steve_

Mounted vertically, the balance center of the battery will be lower than
on my bird, so it won't match the aileron improvements I get.

But since it will be closer to the shaft, vertical mounting should have better
elevator response, which is much more useful

)[/QUOTE]

You were right about the elevator response being improved. I think aileron is just slightly better. The response is so quick: you can just flip the heli around like it weighs nothing. In another post I stated, for a lack of a better description, that it flies lighter. It's really unbelievable how much of a difference mounting the battery vertically made in the "feel" of the helicopter.

One negative thing that I noticed was when a sudden good gust of wind hit the heli it wasn't anywhere near as stable as it was when the battery was mounted lower: certainly not uncontrollable, just less stable. You have to keep in mind though that I'm only running 11 grain (not gram) flybar weights, which is less than 1/5 of the stock weight, with a resultant loss of gyroscopic stability. Much, much more challenging and fun to fly!

Steve, while I was typing this post up you entered post #918! I think we're on the same brain wave-length today!

It's huge. Getting ready to trim it out.

He has not flown it yet.
But DO NOT TAKE ANY TOOLS WITH YOU!

Let it fly like it is - no removing weight, no changing swashplate, skids or similar to improve it

You and I really are on the same brain wave-length today! A little earlier today I calculated your flybar weights at 16.97 grains. I was also thinking that both helis probably fly very similarly. Someone once said something about great minds thinking alike!

Something else I wanted to mention. When I originally modded my 9116 I had moved the battery 3/4" more forward than stock. This made it nose heavy and it handled the wind very well, but I lost a lot of response to rear cyclic.

I just adjusted my swashplate so the heli has a forward movement bias and this also helps somewhat in the wind without really sacrificing anything.

I noticed my tail twitching. It isn't affecting the heading at all and holds well. I just wonder if it has something to do with the gyro placement? Both motors are new.

Hey Pa I'm not so sure that the tail twitch is the placement of the gyro, as I am noticing the same thing on my bird, which hasn't had the board moved (planned project for tomorrow). Could it be the cold weather affecting it??

And yeah I must agree, I find the unweighted flybar a bit much to fly, granted I went from stock flybar to unweighted, as the weights came off yesterday in prep for the project day tomorrow, or when the DD tail stuff gets in...

Are the 9053 blades any stiffer or have less pitch? They look to be the same length.
